You may have to do a front suspension swap using the mid/late 80's stuff, because they do(or at least use to) make drop spindles for 3/4 & 1 ton trucks. Plus you would get the added safety of disc brakes. If that wouldn't bring it down enough cut one coil off the spring. I would also box the frame in the rear where the C-Notch is at least a foot on each side for strength...joe
